DOOR-HANGER TRACK.

Specification of Letters Patent.

Patented Sept. 23, 1913.

Application filed October 26, 1910. Serial No. 589,193.

To all 'whom may concern Be it known that I, I-IENRY C. Sial'rrn, acitizen oit' the United States, residing at Oak Park, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in DoorI^Ianger Tracks, of which the following is aspeciication.

This invention relates to a metallic track used for the support of thewheeled hangers for sliding doors and the purpose oit the invention isto provide an exceedingly strong track; to provide a track and bracketso 'formed that the parts may be conveniently assembled and the bracketspositioned as closely together as desired and to provide a t'ack whichshall be economical to manu- Yfacture.

It has for a long time been sought to produce a door hanger track whichshould have great rigidity both in a vertical and lateral direct-ion,adaptability for association with adjustable 'brackets and which couldbe economically manuit'actured. Some of these objects have been securedin the tubular slotted door hanger track but, obviously the tubularslotted track must be produced either by drawing or bending, and owingto its method of manufacture is much more expensive than the ordinaryso-called flat track consisting' oit' bars which are rectangular' incross section. These ilat bar tracks are objectionable for the reasonthat they are not adjustable with relation to the brackets, furtherbecause of the liability to breakage of the attached brackets inshipment and handling and further because they are weak unless anexcessive amount of metal is used.

My improved door hanger track embodies all of the desirable features ofthe tubular track and of the flat track; that is to say, it is strong,economical of manufacture. can be used with adjustable brackets andatl'ords a secure track in that it is provided With a stay-on feature,namely, a device for preventing the wheeled hanger from jumping thetrack.

My improved track is composed of a rolled section, one edge of whichaffords a track for the hanger and the body of which is provided with alongitudinal groove preterably T-shaped and adapted to receive slidinglytherein the suitably 'formed head of a track supporting bracket. Thebracket and the track receiving,i grooves are disposed in the samevertical plane and the lower edge ot the section may a'l'ord a track or`guiding` surface to receive an under-ruiming,` wheel or hook carried bythe hanger, this providing a stay-on 'feature Ihreterably the sectionwill be such as to present similar track surfaces so that the track maybe used either edge up; in other words, the track is reversible. YVithinthe broader scope of my invention the track surface may be provided uponone edn'e only.

Referring' to the drawings, Figure 1 is a side ele vvation partly insection showingl my improved track with a door .mounted thereou. Fig. 2is a View similar to Fig'. l but showinga a sonlewhat di'tlerent form ofbracket and stay-on device. Fig. 3 is a section of a modification of thetrack shown in 1 and 2, and Fig'. L is a perspective view oi? the 'formoi track and bracket shown in Fig'. l..

The brackets l0, shown in Figs. l and 4C of the drawings, are formed ina single piece say oi. malleable cast iron and are secured by suitablescrews to a wall ill.. These brackets are provided with a bulbous endl2, its contour conforming' to the lri-cove in the track about to bedescribed. The track is adapted to be formed by rolling and comprises amain web 13 which has upper and lower track surfaces 11i, 15. On one of'its lateral sides and midway of its width I pret'cr to form alongitudinal undercut groove 1G, in which the end 1Q, ot' the bracket10, is adapted to be seated. The door 17, is provided with a hanger 18,properly secured thereto by bolts, the hanger as shown carrying; a trackwheel or roller 19, having its periphery tegrooved to correspond to thetrack surface 11i. This roller may be substituted by a sliding;r hook.In Fig. l, I have shown a form oi stay-on which comprises the lowerguide wheel Q0, having, its periphery `grooved to tit the lower tracksurface 15.

The track and bracket oi. my invention are so designed as to beexceedingly simple, yet possessing' the features which will result inthe greatest, strength in a given amount of material, that is, the metalis so distributed that O'reat vertical and transverse strength issecured. Great vertical resist ance is secured by reason of the factthat the point of suspension of the door is in substantially the sameplane as the point of connection of the bracket. One of the importantfeatures is that of adaptability inasmuch as the brackets may be spacedat any desired distance apart. This feature is present in a tubularslotted track, but. as. such track requires either drawing or bending,it cannot be produced so economically as my track which is adapted to berolled and can be produced very rapidly and therefore cheaply.

I have shown in Fig. 2 a bracket of slightly modified construction. Inthis view, the bracket is composed of two parts 21, Q2 united at 23, bya rivet 24. The joined ends are fianged outwardly to form a bearing endfor cooperation with the slot in the track 25. In this View I have alsoshown a different form of stay-on, having eliminated the small trackwheel of Fig. l, the hanger 26, being provided with a bracket, integralor otherwise, having an upturned or hooked portion 28, which is adaptedto fit around the lower surface of the track 25.

In Fig. 3 I have shown a modification of the track illustrated in Figs.1 and 2. In this view the track is composed of the main web 29, havingthe upper flange or track surface 30.

'Obviously my invention is not limited to the exact form of the tracksection or to the exact configuration of groove and bracket head, solong as the several parts are of such form and adapted to so coperate asto secure the objects hereinabove set forth.

I claim: Y

l. A rolled metal track having a longitudinal lm-shaped groove and anupwardly extending marginal rib or flange terminating in a rounded headaffording a track sur face, substantially as described.

2. In a device of the class described, a rolled metal track having anundercut groove adapted to accommodate the enlarged heads of tracksupporting brackets, said track having an upper extension affording atrack surface substantially in the same vertical plane of' the undercutgroove, substantially as described.

3. In a device of the class described, a rolled metal track having alongitudinal bracket groove, and oppositely extending marginal ribs orfianges affording upper and lower track surfaces, substantially as asdescribed.
